'To all whom it may concem Be it known that I, FRED. H. C. MEY, ofBuffalo, in the county of Erie and State of New York, have inventedcertain new and useful Improvements on Metallic Belting for Elevator andConveying Purposes; and I do hereby declare that the followingdescription of my said invention, taken in connection with theaccompanying sheets of drawings, forms a full, clear, and exactspecification which will enable others skilled in the art to which itappertains to make and use the same.

My present invention relates to improvements on metallic belting forelevating and conveying purposes; and it consists in the peculiararrangement of parts and details of construction, as hereinafter firstfully explained, and then pointed out in the claims.

In the drawings heretofore mentioned, Figurel is an elevation of afragment of an elevatorbelt composed of a series of my improved links.Fig. 2 is a like view of a similar belt composed of two lines of links.Fig. 3 is a side elevation. Fig.4 is a transverse section in line a: a:of Fig. 1. Fig. 5 is a similar section in line y y of said Fig. 1. Fig.1, Sheet 2, is an elevation of a fragment of a belt, similar to that ofFig. 1, Sheet 1. Fig. 2 is a plan of a platform-conveyer. Fig. 3 is aside elevation.

Like letters of reference indicate corresponding parts in all thefigures.

A is the bucket-link. It consists of the body A, of an inverted U shape,having on its upper extremity an eye, A, and dividing on its lower endinto two L-shaped branches, at, having each an eye, a, and terminatingin flat tail-pieces or rests a.

Below the upper eye A, which is of a Width corresponding to the distancebetween the eyes a, are two transversely-projecting cross-bar's, a, towhich are secured theusual elevator-buckets G, by means of bolts orrivets passing through apertures d in said crossbars a. v

B is the intermediate link. It is a plain connecting-link, having eyesI) on both its extremities, and a transverse sectional contour,corresponding to that of the body A of the bucket-link A. This linkconnects at one end with the link A, and on its other end with the sidelinks '0, which latter links are likewise plain links, having eyes 0 onboth ex- 'tremities. These links 0 are placed on the sides of theintermediate links B and the eyes A of the bucket-link A, in ordertoprovide in the belting a series of openings, X, wherewith engage therespective sprockets of the driving pulley or wheel to impart motion tothe belting. These sprockets push on the under side, respectively, thelower end of the intermediate links B, and these are therefore madestrong enough to sustain such pressure as may be brought to bearthereon.

The body A, aswell as that of the link B, are, as heretofore described,of an inverted U shape, or recessed on their lower sides, so as to admitthe bolt heads or nuts within, and to present a perfectly flush and evensurface on the under sideof the belting.

.D is a substitute link for the bucket-link A, it being in all respectsidentical with that,

'except that it has no cross-bar a nor tailpieces a. This link is placedinto the belting instead of the bucket-link whenever these bucket-links(were they arranged in their order) would be too close together. In thiscase every second one of the repeating series will contain abucket-link, while the interme? diate series will be provided with thesubstitute link, which, should the capacity of a belt be required to beincreased, may be readily removed and the bucket-link substituted, andthe capacity of the belt thereby doubled.

The links heretofore described form a series, and these are repeated asoften as is necessary to produce an elevator-belt of the desired length.

It is obvious that my belting may be used for all the various purposesof conveying, elevating, &c. Thus, in addition to its adaptation as anelevator-belt, it may be used as a platform-conveyer by substituting aplatform,

' K, for the bucket G, as illustrated in the various figures of Sheet 2.In this case I shall, however, dispense with the link A and use itssubstitute, the link D, so that the repeating series are composed of thelinks D, G, and B,

and secure the platform K to the respective A links by means of boltspassing through the apertures D in the bodies of said links.

All the belt-links are produced complete in the process of casting ofgray iron and subsequent annealing, so that the eyes, which are 'at oncecast in the links, are all solid. This stated. 3. In metallic belting, alink having its.

body formed in an inverted U shape, and provided with eyes forattachment, substantially as and for the purpose specified.

4. The combination, with the link A, of the links B and O, with orwithout the substitute link D, as and for the use and purpose stated.

5. In metallic belting, a link having a tailpiece or rest projectingbeyond the point of attachment of the intermediate links, as specified.

6. A bucket-link having the cross-bar a formed in one piece with thebody of the link, and raised above the base-line, as and for the objectstated.

7. A bucket-link having the cross-bar a and one or more bodies, A,provided with solid eyes, all formed entire in the process of casting,as specified.

In testimony that I claim the foregoing as my invention I have heretoset my hand and affixed my seal in the presence of two subscribingwitnesses.
